Deck Cleaning and Sealing on the Surf Coast – Professional Timber Restoration

Your deck is one of the most exposed parts of your home. On the Surf Coast, constant sun, salt air, moisture and foot traffic quickly break timber down, leaving it grey, stained, slippery and vulnerable to rot. Professional deck cleaning and sealing is the most effective way to restore the look of your timber and protect it long term.

At Sea Sweep, we provide professional deck cleaning and sealing across Torquay, Bellbrae, Anglesea, Aireys Inlet, Fairhaven, Eastern View and Lorne, helping homeowners revive tired decks and protect them from harsh coastal conditions.

What Is Deck Cleaning and Sealing?

Deck cleaning and sealing is a full restoration and protection process that includes:

  • Deep cleaning of timber boards

  • Removal of black mould, algae and grime

  • Stripping old residues and surface contamination

  • Brightening and neutralising the timber

  • Application of professional timber oils or sealers

The cleaning stage restores the timber’s natural colour and removes contaminants. The sealing stage penetrates and protects the wood, locking out moisture and UV damage while enhancing the timber’s appearance.

The result is a deck that looks dramatically better and lasts significantly longer.

Professional Techniques That Restore, Not Damage

Decks are easily ruined by incorrect pressure, harsh chemicals, or rushed work. Sea Sweep uses professional restoration methods designed specifically for timber.

Our deck cleaning and sealing process typically includes:

  • Pre-treatment to break down mould, organic growth and embedded grime

  • Controlled pressure cleaning to deep-clean boards without shredding timber fibres

  • Timber brightening to restore colour and neutralise the surface

  • Full rinse and drying period

  • Application of professional-grade deck oil or sealer by brush, roller or spray

  • Even penetration, no patchy coats, no sticky buildup

We tailor every job based on timber type (pine, merbau, spotted gum, hardwoods), condition, sun exposure and previous coatings.

This ensures the timber is not only clean, but properly prepared to accept oil and perform long term.

What Deck Cleaning Removes

Our professional deck cleaning service removes:

  • Black mould and mildew

  • Green algae and slippery bio-growth

  • Dirt, sand and coastal residue

  • Tannin bleeding and weather staining

  • Old oil contamination and surface grime

  • Construction dust and renovation residue

Once cleaned and brightened, decks regain their natural tone and are ready to be sealed correctly.

Why Sealing Your Deck Is Critical

Cleaning alone is not enough. Bare timber rapidly absorbs moisture and UV, leading to:

  • Cracking and splitting

  • Accelerated greying

  • Warping and cupping

  • Rot and premature timber failure

Deck sealing forms a protective barrier that:

  • Repels water

  • Reduces UV damage

  • Slows down mould growth

  • Enhances timber colour and grain

  • Extends the life of the deck

On the Surf Coast, sealing is not cosmetic — it is essential maintenance.

Ideal for Residential Homes, New Decks & Renovations

Sea Sweep deck cleaning and sealing is ideal for:

  • Routine deck maintenance

  • Grey, tired or slippery decks

  • Homes preparing for sale or rental

  • New decks needing first-time sealing

  • Renovations and post-build clean-ups

  • Coastal homes exposed to salt and wind

We work on small residential decks through to large entertainment areas, balconies, staircases and pool surrounds.

Deck Cleaning and Sealing Pricing – What to Expect

Every deck varies in size, timber type and condition, but as a general guide:

A standard residential deck often falls in the range of $800–$2,500+ for professional cleaning and sealing.

Factors that influence pricing include:

  • Total square metres

  • Timber type and condition

  • Heavy mould, blackening or contamination

  • Access and layout

  • Number of oil or sealer coats required

  • New timber vs restoration work

We provide clear, upfront pricing and only recommend what your deck actually needs.
